[0249] As shown in FIG. 17 zymosan [1 mg per mouse in 200 l H2O] induced a massive influx of leukocytes detected in lavage 24 h post-zymosan. Pre-treatment of the animals with LXA4 [5 ng/g, 200 l i.p. 30 minutes prior to zymosan injection and again, 1 hour after zymosan injection] significantly [p=0.0169] attenuated this response. Mean of total cell numbers=4.27106/ml [basal]; 5.9107 [vehicle pretreatment and zymosan]; 2.18107 [LXA4 pretreatment and zymosan]. Pretreament with (R) and (S) epimers of 9 also attenuated cell influx: 2.5107/ml [pretreatment with (1R)-9 and zymosan; p=0.0368, relative to zymosan alone]; 1.16107 (1S)-9 [p=0.0048 relative to zymosan alone]. Importantly, (1R)-9 and (1S)-9 were administered at doses of 1.7 ng/g using the same regimen as LXA4. As anticipated the leukocyte influx was predominantly neutrophil [PMN]. PMN numbers were reduced to 35, 44 and 20% maximum response by LXA4, (1R)-9 and (1S)-9 epimers respectively.

[0250] Effect of LXA4 1 and imidazole-lipoxin analogues (1R)-9 and (1S)-9 on murine zymosan-induced peritonitis. Peritonitis was induced in groups of 5 male C57BL6/J mice by injection of zymosan (Sigma) i.p. (1 mg per mouse in 200 l H2O). Mice were treated with LXA4 1; (5 ng/g); (1R)-9 (1.7 ng/g) or (1S)-9 (1.7 ng/g) (200 l i.p.) 30 minutes prior to zymosan injection and again, 1 hour after zymosan injection. Treatments with LXA4 1, (1R)-9 and (1S)-9 are designated A, B and C respectively. Peritoneal cells were collected by lavage 24 hours after injection of zymosan. Cells were incubated with LIVE/DEAD Fixable Aqua stain (Molecular probes, Invitrogen) to isolate dead cells. Data shown are total cell counts/ml. Surface marker expression on peritoneal cells was assessed by flow cytometry with data collection on a CyAn (Beckman Coulter). Data were analyzed using FlowJo software (Tree Star). Cells were stained with BD Biosciences mAbs; Siglec-F-PE (E50-2440), F4/80-FITC (BM8), eBiosciences mAb; CD11b-PerCP (M1/70) and BioLegend mAbs; CD206-PECy7 (C068C2) and Ly6G-APCCy7 (1A8). Using appropriate isotype-controls, quadrants were drawn and data plotted on logarithmic scale density- or dot-plots to investigate the relative % of PMN, eoisiophils, M1 and M2 macrophgaes. The relative propotion of each cell type was unchanged by treatment with LX or LX analogues.

Paw swelling was monitored over time [4-72 h] using an external lever gauge [Kroeplin]. Data are presented as mean+/SEM, n=3 mice/treatment group.

EXAMPLESTESTING

[0253] The aims of the experiments were to evaluate the anti-inflammatory, pro-resolving and anti-fibrotic properties of stable LXA.sub.4 analogues using a series of in vitro models of inflammation, resolution and fibrosis in order to find useful leads for the development of novel therapeutic modalities.

[0254] The structure of LXA.sub.4 was modified to prevent: (i) reduction of the C.sub.9-C.sub.14 unit (at C.sub.13-C.sub.14); and (ii) oxidation of the C.sub.15-C.sub.20 unit (at C.sub.15 and C.sub.20).

[0255] The LX analogues were obtained by modifying the native compound as follows: [0256] a) methyl esterification at C1 or lactonization of the upper chain; [0257] b) replacing of the triene core with the heteroaromatic quinoxaline or isoquinoline groups; and [0258] c) shortening or extending the length of the lower chain (from 6C of LXA4 to 4C or 8C).

[0259] In particular, quinoxaline- and isoquinoline-derivatives (as shown in Table A below) were tested for their anti-inflammatory properties.

Experimental Design

[0270] The experiments were based around a model which utilised 110.sup.5/ml THP-1 monocytes stably expressing NFkB luciferase reporter gene (LUCIA).

[0271] Anti-Inflammatory Activity

[0272] Anti-inflammatory activity was assessed by testing 10 analogues (6 quinoxalines & 4 isoquinolines) in presence & absence of lipopolysaccharide (LPS). For each analogue, a dose-response from 10.sup.12 M up to 10.sup.6 M was performed. The vehicle control corresponded to 0.1% Ethanol. NFkB activator, Heat-Killed Listeria Monocytogenes (HKLM) (10.sup.7 cells/ml), were used as positive control for luciferase induction. 10.sup.6 M Dexamethasone (Dex) was used as positive control for luciferase inhibition. 10.sup.1 M Benzo-lipoxin A4 (BLX) was used as positive control for LXA.sub.4 analogues.

[0273] Cytotoxicity Prior to functional assay testing, all compounds were screened for any cytotoxic effect, in the presence & absence of LPS, measuring the level of lactate dehydrogenase (LDH) released at A.sub.490nm.

[0274] Statistical Analysis

[0275] A 2-tailed, assuming unequal variance T-test analysis was performed on three independent experiments for each assay. P-values were considered significant when p<0.05. If p<0.05, then * or $; if p<0.01, then ** or $$ or ##; if p<0.001, then *** or $$$ or ###.

[0276] Results

[0277] The results of the experiments are shown in the appended figures.

[0278] In particular, with reference to FIGS. 4, 10 and 11, the dose-response for LXA.sub.4 vs quinoxaline-derivatives for LPS-induced NFKB luciferase activity is shown. Cells were seeded in 96-well plates and pre-treated with increasing doses of LXA.sub.4, analogues or controls for 30 min, followed by 24 h of co-incubation with 50 ng/ml LPS. LXA.sub.4 (denoted by black bars in the figures) maximal inhibition is reached at 100 nM (by 241.1% relative to LPS). CT4-43 significantly reduced ($=p<0.05) NFkB activity, compared to the corresponding LXA.sub.4 dosage, at 1 and 10 nM (respectively, by 38.28.2% and by 34.84.2%). CT4-68 significantly reduced ($$=p<0.01) NFkB activity, compared to LXA.sub.4, at 1 uM (by 28.96.6%). CT4-63 had its maximum inhibition at 1 nM (by 22.87.4%), but not significantly different from LXA.sub.4. The relative S epimers presented similar or slightly less potent response (data not shown). (*=statistical analysis vs LPS; $=statistical analysis vs LXA.sub.4)

[0279] With reference to FIGS. 7 and 12, the dose-response for LXA.sub.4 vs isoquinoline-derivatives for LPS-induced NFkB luciferase activity is shown. In particular, it was shown that DM-163-RB3 significantly reduced ($=p<0.05) NFkB activity, compared to the corresponding LXA4 dosage, at 10 nM and 100 nM (respectively, by 35.46.1% and by 37.99.7%). DM-178-SB4 significantly reduced ($=p<0.05) NFkB activity, compared to LXA.sub.4, at 1 uM (by 26.88.7%). Furthermore, in the absence of LPS-challenge all the quinoxalines and isoquinolines tested did not induce NFkB activity, in contrast to HKLM stimulation (data not shown). (*=statistical analysis vs LPS; $=statistical analysis vs LXA.sub.4)

[0280] With reference to FIGS. 13 and 14, there is shown the cytotoxicity of quinoxaline- and isoquinoline-derivatives in presence and absence of LPS-challenge. The cells were treated as described above and, after 24 h, supernatant was collected and LDH activity assayed. LPS was associated with a 40% induction of LDH activity. This response was found to be significantly attenuated by LXA.sub.4 analogues. Similarly, the benzo-lipoxin A.sub.4 (Blx) analogue significantly (p<0.001) decreased LPS activity. In contrast, Dexamethasone (Dex) significantly (p<0.001) increased LPS response, due to an additive effect. (* or $=statistical analysis vs LPS)

SUMMARY

[0281] The most effective analogue identified in the experiment was the quinoxaline-derivative (1R)-CT4-43, which was found to be significantly more potent than LXA.sub.4 in reducing LPS-induced NFkB inflammatory activity. Variation of the lower chain length (longer or shorter) did not appear to lead to enhanced activity of quinoxalines. Among the isoquinolines, (1R)-DM-163-RB3 was found to be the most potent and, overall, 1,3-isoquinolines displayed stronger anti-inflammatory properties than 1,4-derivatives. Cytotoxicity of all the analogues analysed suggests protection from LPS-induced damage.

[0282] With reference to FIG. 15, there is shown the dose-response for LXA.sub.4 vs the imidazole-derivative KG-5-22 for LPS-induced NFkB luciferase activity. In particular, it was shown that KG-5-22 significantly reduced (respectively, $$=p<0.01 and $$$=p<0.001) NFkB activity, compared to the corresponding LXA4 dosage, at 1 pM and 10 pM (respectively, by 43.78.9% and by 41.39.0%). Furthermore, with reference to FIG. 16, it is shown that in the absence of LPS-challenge the tested imidazole-derivative did not induce NFkB activity, in contrast to HKLM stimulation (data not shown). (*=statistical analysis vs LPS; $=statistical analysis vs LXA.sub.4).
